Claims. (Cl. 11G-18) This invention relates to incinerators and more particularly to outdoor type domestic incinerators.

An important object of the invention is to provide an incinerator which is easily charged with refuse and the like, the combustible portions of the refuse being readily ignited, and safely burned and the non-combustible portions being discharged from the incinerator without causing them to be scattered about.

Another important object is to provide an incinerator having a swinging closure which is supported against accidental closing when the closure is in an open position for charging the incinerator and is supported in 'a dierent position, against accidental closing when the closure is in an open position for the discharging of unburnt material from the incinerator.

Still another important object is to provide an incinerator, the refuse-containing housing of which may be rocked in order to cause the contents to be rolled about in order to better promote combustion and, if desired, also shaken up or jarred. Sometimes, halfburnt material or incombustible material will close so many of the openings in foraminous housings of incinerators and adhere to the walls of the housings, that combustion lis retarded and a more vigorous action than mere rocking or rotating of the housing is required. This can be lessened or remedied by jarring the housing.

Another important object is to provide incinerators as described above, having spindle-accommodating bearing members, of special construction, each adapted to accommodate two spindles at the same time but from which members one or both may be readily removed and replaced. The construction is such that one pair of spindles attached to the closure `of the incinerator may be readily removed from the bearing members upon opening of the closure for charging the housing, or both pairs may be readily removed in order to remove the entire housing and its closure for repairs and the like.

Yet 'another important object is to provide an incinerator as detailed above which is associated with a removable pit or incombustible material-receiving receptacle which cannot be moved out of position beneath the housing until the incombustible material has been discharged from the housing into the receptacle.

Still another important object is to provide brace means for the spindles which has an additional function in connection with the operation of the incinerator.

`Other objects and advantages of the invention will be apparent during the course of the following detailed de scription of the invent-ion, taken in connection with the accompanying drawings, forming portions of this disclosure, and in which drawings:

Figure l is a front elevational view of the closed incinerator.

Figure 2 is an end elevational View thereof but showing, in dotted lines, the closure of the incinerator in an open position for the introduction of refuse into the incinerator.

Figure 3 is a view, mostly in vertical transverse section, with the incinerator open and in a dumping position.

Figure 4 is an enlarged fragmentary vertical sectional view, substantially on the line 4 4 of Figure 3.

Figure 5 is an enlarged fragmentary sectional View substantially on the line 5-5 of Figure 4.

The ncinerator is illustrated, as a preferred embodiment thereof, as comprising a support structure 10; refuse-receiving means 11 rotatably carried by thesupport structure 1i), and in which the combustible portions of the refuse are burned; pivot means 12 for movements of the means 11 upon the support structure 10; and means 13 for receiving the unburnt or non-combustible portions of the refuse from the means 11, and which means 13 is also supported by the support structure 1i).

Preferably, the support structure lil includes a plurality of spaced-apart uprights 2i? and 21 which may be of angle iron, providing spaced-apart iront legs 20 and rear legs 21, of which the latter are preferably much longer than the legs 2Q to provide, in cooperation with portions of the means 12, stops or abutments for the means 11, as shown in dotted lines in Figure 2 and as subsequently described.

In addition, the support structure 10 includes a front longitudinally-extending horizontally-disposed cross member 22 secured, as by welding, to the front legs 2i) spaced well below their upper or top edges of the latter, since closure or cover wall 51 of the means 11, to be subsequently described, is adapted to be swung into one of two open positions in the upper part of the support structure and then forwardly between the legs 20. This cross member 22, in addition to its function as a brace and support for the legs 2t) also provides support for the means 13 as will be described. A second or rear cross member 23, substantially like the member 22 connects the legs 21. Above the cross member 23 is preferably a third substantially horizontal cross member 24, secured, as by welding, to the legs 21. in addition, there is provided suitable horizontal end cross members 25 secured, as by welding, to the legs 20 and 21 preferably at the upper ends of the legs 2t? and intermediate the ends of the legs 21, as may be appreciated in Figure 2.

`The cross members 22 to 25 may be of angle iron construction. Suitable oorner braces 28 may be provided to connect the legs Ztl and end cross members 25 as well as the legs 21 and these end cross members. Other corner braces 29 may be provided to connect the legs 21 and upper rear cross members 24. These may be rigid metallic straps, welded in place. rl`he support structure 1t), thus provided, forms a hollow frame, and carries bearing members 30 of special construction, best shown in Figures 2 and 3, and rigidly mounted upon the end cross members 2S to extend upwardly therefrom. Preferably, eac'h bearing comprises a stout metallic strap with its end portion formed into a pair of feet .31 disposed upon the upper face of the end cross member 25, upwardly and inwardly portions 32 extending from the feet portions, a minor bight portion 33 at the upper end of the portion 32 and a curved portion (preferably arcuate) 34 extending downwardly with its lowermost part (major bight portion) disposed upon the upper face of the end cross member 25. Since the two minor bight portions are spaced apart, there is provided a mouth or space 35 for purposes later described. The straps, at the curved portions 34 dene the bearing surfaces or faces of the bearing members 30 which are somewhat open loop shaped. Of course, each bearing 3i) is disposed intermediate the ends of the end cross members 25, preferably half way between the ends.

Referring now to the refuse-receiving means 11 rotat ably carried by the support structure 10 and in which the combustible portions of the refuse are burned, the same includesan elongated housing 40, having opposite end walls, each comprising two sections 42 and 43, each semicircular in plan and having facing reinforcing edges 44, a vforaminous side wal-l 45, preferably semi-circular .in transverse section, with Yfront Vand rear side edge reinforcing members 46 and 47 respectively, a Vcover or vclosure 51 preferably semi-circular in transverse section and having front -and rear edge reinforcing members 52 and 53, with the two second end -wall sections 43 rigidly secured to the ends of the side wall 45, and the two iirst end wall sections 42 rigidly secured to the ends of the closure wall 51, in any approved way, such as by welding. Thus, the side wall 45 with the end wall sections 43 provide substantially one half of a cylinder, and the closure wall 51 and end wall sections 42 provide substantially the other half of a cylinder, whereby a combustion chamber 54 is provided. Preferably the closure wall 50 is also foraminous like the side wall.

Means 55 to connect the closure 50 to the side wall 45,

at the rear portion of the support structure may be a hinge construction, such as a plurality of leaf hinges, with one like leaf of each secured to the rear reinforcing edge 47 and the other leaf of each secured to the reinforcing edge 53, whereby the closure 50 may be swung upwardly and lrearwardly when the side wall 51 is lowermost, so that refuse may be introduced, as dumped, into the chamber of the housing 40, whereupon the closure 50 may be closed, thus forming a closed hollow cylinder.

Suitably disposed along the lengths of the reinforcing edges 46 and 52 so that they are normally at the front portion of the support structure, may be hand hold projections or lugs 60 having finger-receiving slots 61. If desired, suitable means 65 may be provided to releasably secure the closure in a closed position. This may consist of a conventional padlock chain 66 extended through the linger-receiving slots and the two end portions oif the chain secured together as by a conventional padlock 67.

Pivot means 12 Ifor rocking of the means 11 upon the support structure 1t) includes a spindle or pivot member 71 rigid with and extending outwardly from each end wall section 43 and adapted to be carried by the bearing members 30 and rotate on the curved portions 34 thereof. These are disposed intermediate the ends of the end wall sections, preferably midway the ends, and close to the reinforcing edges 44 of the sections 43. The means 12 will be referred to later.

Associated with the two pivot means 12 are two second spindles 72 rigid with and projecting outwardly from the two end wall sections 42. Thediarneter of each spindle 72 is less than the widths of the mouths 35 so that the spindles may enter or exit from them as the closure is swung out or into closing positions. While the spindles 72 are primarily provided as stops for the closure 5i) when in an open position for charging of the incinerator as in dotted lines in Figure 2, where the spindles 72 engage the yupper portions of the uprights 21, the spindles 72 may function incidentally if it is desired to stake up the contents of the housing to promote better combustion, since the housing may be rotated 360 or less degrees if desired, with the closure closed and the spindles 72 functioning as pivots during a part of the rotation of the housing. However, generally, the spindles 7i provide for rotative support of the housing. Such rotative support is when the housing maybe rocked, say, 15 degrees in order to agitate the burning contents, or rotated on the spindles 71, into the position shown in Figure 3 Where the mouth of the housing 40 is lowermost. In rotating the housing into the position shown in Figure 3, the hand-hold 60 of the closure 50 may be grasped `and the closure rst swung upwardly until the spindles 72 clear the mouth 35 and the closure may then be drawn forwardly and downwardly, causing rotation of the housing through 180 4 of `arc and thus dumping the incombustible contents from the housing.

In order to brace the spindles 71 and 72, I prefer to provide a rigid metallic brace plate 73 for each spindle, one of which plates 73 is shown in vertical section in Figure 4 and in plan in Figures 2 and 3. The upper portion of the plate may be Vwelded to the outer face of an end wall section, with the intermediate portion of the plate extending outwardly and downwardly and provided, at its lower part, with an opening 74 snugly accommodating an intermediate portion of the spindle and the latter maybe welded thereto. The lowermost portion of the plate may be bent rearwardlyas at 74a and welded to an outwardly extending ange74D carried by the associated end wall section. Thus the brace plate supports the spindle intermediate the ends of the latter rather than adjacent an end and provides more adequate support for the spindle. In addition to their bracing functions, the plates 73 act as stops to prevent the housing moving longitudinally to such a position that a spindle would move out of a bearing member and cause the housing to drop.

I prefer to provide a receptacle means 75 for receiving the incombustible contents from the housing. This is preferably a pan provided with a bottom wall 76, upwardly diverging side walls 77 and end walls 73 which may be substantially vertical, all defining an upwardlyopening receptacle 79. The spread of the walls 77 are preferably such that their upper ends are closely adjacent the front and rear cross members 22 and 23 respectively, and provided with inverted J-shaped hook members 80 adapted to hook over the upstanding edge portions of the elongated angle irons 36 carried upon the upper surfaces of the cross members 22 and 23, to slide therealong. I may provide a hand-hold projection 81 at each end of the receptacle, secured to and extending outwardly from the walls 78.

It will be noted, in comparing Figure 2 with Figure 3, that the receptacle 75 can be removed only when the housing 40 is in the discharge position of Figure 3, and cannot be accidently removed while the receptacle is in the position shown in Figure 2, since the positions of the respective end wall sections 43 and end walls 78 would prevent this.

In use, the closure 40 may be swung upwardly and rearwardly until the spindles 72 engage the upper portions of the legs 21 and the refuse or other material to be treated is introduced to the chamber of the housing 10 whereupon the closure may be lowered to a closed posi- 4tion and, if desired, secured in its closed position. Ignition of the material may be effected by introducing a flame (as of a match) through the openings in the wall 45. Smoke will exit from the openings in the walls 45 and 51. If it is desired to agitate the material within the housing 40, the hand-holds 60 may be grasped and the entire housing rocked upon the spindles of pivot means 12. More drastic agitation may be effected by a 360 or less rotation of the housing with a consequent jarring of the contents. Ash and small incombustible particles will sift through the openings in the housing walls but larger incombustible material must be removed by swinging the closure 50 upwardly that the spindles 72 will clear the bearing members 30, and then forwardly. This will cause partial rotation of the housing into the position shown in Figure 3, with the closure disposed outwardly closed position with the spindles 72 again within the bearing members 30.

Various changes in the size, shape and arrangement of parts may be made to the form of invention herein shown and described, Without departing from the spirit of the invention or scope of the claims.
